LUBRICATOR FOR CAW-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 708,306, dated September 2, 1902. Application tiled October Z4, 1901. Serial No. 79,763. (No model.)

vention, such as will enable others skilled iu the artto which it appertains to make and use the same.

My invention relates to car-trucks, and has for its object to provide improvements in the frame, to provide improved means for` lubrieating the bearings of the axles, to provide means to permit the'acceleration of speed of the Wheels on one side of a truck in passing curves, whereby injury tothe rail andwheels caused by the running or crowding of the wheels against the rail in the usual construction of an axle made in one piece is avoided,` and to provide a truck which is simple and inexpensive in construction and effective in use. l

My invention consists in the construction, combination, andarrangenient of parts more fully hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a top plan view. Fig. 2 is a side View; Fig. 3, a vertical longitudinal sectional view on the line .r of Fig. l; and Fig. 4, a vertical cross-section on line fy y of Fig.

` l, on an enlarged scale, omitting the truckframe.

Referring to the drawings, in which like letters of reference indicate corresponding parts throughout the several views, A designates the side frames of the truck, connected by transoms B.

C designates short frames located between the side frames and secured to the transoms at D, near each end thereof.

E designates wheels secured upon or made integral with short hollow axles F, having reduced portions G forming the journals.

II designates lubricant-receptacles for the journals on the outer ends of the axles, mounted in guides I in the frame A and having a lid J.

K designates lubricant-receptacles for the journals on the inner ends of the axles,

mountedY in guides L and extending from the inner end of one axle to the inner eind of the axle on the opposite side of the frame and having lids M.

N designates springs interposed between the lubricant-receptacles and the frames for the purpose of cushioning the truck.

The short frames C are each preferably cast or formed in one piece, but may be otherwise constructed, one of these frames being employed for each end of the inner lubricant- Areceptacles and secured to the sides of the transoms, so as not to extend across the transoms and interfere with the free movement of the holsters.

It will be readily seen that, as the axles are hollow and extend from the outsidelubricant-receptacles into the inside lubricantreceptacles, if lubricant is supplied to any one or more of the lubricant-receptacles it will be equally distributed to all the other" lubricant-receptacles communicating therewith, thus greatly lessening the danger of hot boxes and the time required to till the receptacle, as a great amount of lubricant can be carried, and it is only necessary for the oiler to examine one lubricant-receptacle at each end of the truck to ascertain the condition of all the lubricant-receptacles. It will also be seen that through the medium of the lubricant-receptacles Kthe axleswill be held in alinemeut and the frame greatly strengthened.

My car-truck enables a car to run smoothly around sharp curves, reduces the power necessary to pull, and preventsbreaking from torsional strain and reduces the friction.

I do not wish to be restricted to theprecise construction herein shown and described, as the same may be varied somewhat without departing from the spirit of my invention.

Having thus described my invention, what I claim isl. A car-truck provided with wheels each of which is provided with an independent hollow axle, areceptacle connecting and furnishing communication between the inner ends ot' the axles, and a receptacle on the outer end of eacl1 axle, whereby lubricant supplied to any one of the receptacles will be distributed to all the others, substantially as described.

IOO

2. A car-truck provided with wheels each of which is provided with an independent hollow axle, lubricant-receptacles mounted on and surrounding the outer end of each axle,and an independent lubricant-receptacle between said Wheels which furnishes communication between the inner ends of the axles, substantially as described.

3. Acar-truck comprising wheels each having an independent hollow axle, side frames provided with lubricant-receptacles supported on the outer ends of said axles, meansl substantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
